Never tried shrooms yet, but had a similar experience with Amelie. Just after the break up I held myself okay, like a functional adult, but when there was a scene where Amelie felt like she’s imagining things and he’d never come for her, I teared the hell out of me, nearly vomited my guts out from the sudden strike of sadness. Doubt I’d recomend it in an altered state of mind tho - the movie is already wicked. Yet, it’s very, very sweet. If you’d come around it, feel free to write me back about how it felt, or maybe do a post here on the fediverse.
